Ilminism (Hangul: 일민주의; Hanja: 一民主義; RR: Ilminjuui;), frequently translated as the One-People Principle, was the political ideology of South Korea under its first President, Syngman Rhee. The Ilmin principle has been likened by contemporary scholars to the Nazi German idea of the herrenvolk (master race), and was part of an effort to consolidate a united and obedient citizenry around Rhee's strong central leadership through appeals to nationalism and ethnic supremacy.
The concept of the One-People Principle was developed primarily by Minister of Education An Ho-sang, who studied philosophy at the University of Jena in Germany during the late 1920s.
The One-People Principle has been likened to the German ideology of the herrenvolk (master race), constituting an effort to build a loyal and obedient citizenry through ethnic homogeneity and brazen appeals to nationalism. The idea for a Korean adaptation of this Germanic idea emerged from the works of philosopher An Ho-sang, the Minister of Education under Syngman Rhee, who studied at the University of Jena in Germany during the late 1920s.
The Ilmin Principle became the central ideology of Rhee's National Society and its successor, the Liberal Party, established in 1951.
The One-People Principle was based around a four-point political program, including elimination of formal discrimination between the nobility and the masses, the economic equalization of rich and poor through land reform, social and political equality of the sexes, and an end to discrimination between North and South or the urban capital and the rural provinces. An end to partisan politics was posited, in favor of a united people behind a de facto one-party state.
